Whenever a client connects, the server creates a :class:`ServerConnection`, performs the opening handshake, and delegates to the ``handler``. The handler receives a :class:`ServerConnection` instance, which you can use to send and receive messages. Once the handler completes, either normally or with an exception, the server performs the closing handshake and closes the connection. :class:`WebSocketServer` mirrors the API of :class:`~socketserver.BaseServer`. Treat it as a context manager to ensure that it will be closed and call the :meth:`~WebSocketServer.serve_forever` method to serve requests:: def handler(websocket): ... with websockets.sync.server.serve(handler, ...) as server: server.serve_forever() Args: handler: Connection handler. It receives the WebSocket connection, which is a :class:`ServerConnection`, in argument. host: Network interfaces the server binds to. See :func:`~socket.create_server` for details. port: TCP port the server listens on. See :func:`~socket.create_server` for details. sock: Preexisting TCP socket. ``sock`` replaces ``host`` and ``port``. You may call :func:`socket.create_server` to create a suitable TCP socket. ssl_context: Configuration for enabling TLS on the connection. origins: Acceptable values of the ``Origin`` header, for defending against Cross-Site WebSocket Hijacking attacks. Include :obj:`None` in the list if the lack of an origin is acceptable. extensions: List of supported extensions, in order in which they should be negotiated and run. subprotocols: List of supported subprotocols, in order of decreasing preference. select_subprotocol: Callback for selecting a subprotocol among those supported by the client and the server. It receives a :class:`ServerConnection` (not a :class:`~websockets.server.ServerProtocol`!) instance and a list of subprotocols offered by the client. Other than the first argument, it has the same behavior as the :meth:`ServerProtocol.select_subprotocol ` method. process_request: Intercept the request during the opening handshake. Return an HTTP response to force the response or :obj:`None` to continue normally. When you force an HTTP 101 Continue response, the handshake is successful. Else, the connection is aborted. process_response: Intercept the response during the opening handshake. Return an HTTP response to force the response or :obj:`None` to continue normally. When you force an HTTP 101 Continue response, the handshake is successful. Else, the connection is aborted. server_header: Value of the ``Server`` response header. It defaults to ``"Python/x.y.z websockets/X.Y"``. Setting it to :obj:`None` removes the header. compression: The "permessage-deflate" extension is enabled by default. Set ``compression`` to :obj:`None` to disable it. See the :doc:`compression guide <../../topics/compression>` for details. open_timeout: Timeout for opening connections in seconds. :obj:`None` disables the timeout. close_timeout: Timeout for closing connections in seconds. :obj:`None` disables the timeout. max_size: Maximum size of incoming messages in bytes. :obj:`None` disables the limit. logger: Logger for this server. It defaults to ``logging.getLogger("websockets.server")``. See the :doc:`logging guide <../../topics/logging>` for details. create_connection: Factory for the :class:`ServerConnection` managing the connection. Set it to a wrapper or a subclass to customize connection handling. rzunsupported compression: zmissing path argument)familyz(path and sock arguments are incompatibleTF) server_sidedo_handshake_on_connectc t } s/|jtjtjd\|j |j t|tjsJ|j|j dd} dfd }t |t }J||j|j   jy#t$r|jYywxYw#t$r?|j j#ddjt$j&YywxYw)NTc>J|jusJ|Sr)r+)r+r connectionrs r-protocol_select_subprotocolz@serve..conn_handler..protocol_select_subprotocols2 .999#z':'::::-j,GGr.)rrrrrHrr?r"zconnection handler failedr1)r+rrzSequence[Subprotocol]rXzOptional[Subprotocol])r setsockoptr* IPPROTO_TCP TCP_NODELAY settimeoutrLrPssl SSLSocket do_handshakerrrNr=rr?r@r INTERNAL_ERROR)r{r|deadlinerr+rr#rrrfr?rrrrIrJrrKrrrs @r- conn_handlerzserve..conn_handlersL)B  2 2F4F4FM& 0 0 23!$ 666!!#% ("-H,H"7H+H&%)#> !H%0 00*+J     "    J       JJL    7 OO ! !"= !
